Either you have change your language by mistakenly or somebody changed who have your Facebook password,From my point of view if you want to have any suggestion then i prefer you to change at First your Facebook profile "PASSWORD",then go to the "ACCOUNT SETTINGS"at the top most right side of your profile where from you used to "Log-out" your profile,Then under "ACCOUNT SETTINGS" you will see the option "LANGUAGE" and then change it as per your requirement,But for your own protection At First you should change the "PASSWORD".
